Haruj Volcanic Field Spread Out Across Central Libya

The large, brown area visible here, surrounded by Sahara Desert sands, is the Haruj, a large volcanic field in central Libya. The immense field spreads out across 45,000 km2 (17,000 sq mi) of the country. It contains about 150 volcanoes, including numerous basaltic scoria cones and about 30 small shield volcanoes, along with craters and lava flows.
